While ZAGGsparq is the #1 selling charger (and ships for free to all USA addresses), there’s another charger on Kickstarter called Fuel. At 1″ by .5″, it’s not meant to give your phone a full charge, but to give you the boost you need to make another phone call, send a few texts, or use your gps to get to your destination. The creators are marketing it as a back-up battery. The size allows you to keep it anywhere you go – on your keychain, in your pocket, or you could even hoard hundreds of them in a small bag.

The design mimics a small gas can. Exactly like the ones you use when you run out of gas and have to make the long walk to the nearest gas station. Only with this, when you run out of “gas” on your cell phone, your refill is already in hand. The battery can give an average cell phone additional talk time of 20-30 minutes or a few hours of standby time, depending on your phone and the type of use.

For a pledge of $15 or more, you will be one of the first to receive this tiny, and super functional battery/keychain.
